Global change impacts on plant-soil feedbacks: consequences for ecosystem functioning and stability

Research Project

Climate change is known to influence both plants aboveground and the soil biota belowground; however, it is unclear how this will affect the interactions among these tightly linked communities. Specifically, climate change impacts on belowground assemblages via effects on individual plant species and edaphic properties can cause shifts in plant-soil feedbacks (PSFs) that in turn alter plant community dynamics with potential long term impacts. My assumption is that climatic changes, and in particular drought, alter aboveground-belowground linkages, including shifts in PSFs, with potential implications for plant species diversity and ecosystem functioning. For example, shifts in soil assemblage structure and activity under drought may slow down litter decomposition and contribute to immobilization of soil nutrients, which in turn will reduce plant growth. Our ability to predict drought impacts on ecosystems is, however, still limited by insufficient knowledge of plant-soil biotic interactions. For this reason, the overarching aims of my PhD project are to i) explore the impact of drought on PSFs at a species and community level across plant functional groups; ii) measure the role of historical rainfall condition in moderating potential effects of drought on PSF; iii) Assess shifts in PSF governed by insect herbivory (foliar and root) under drought conditions and, lastly, iv) investigating litter and microbially mediated influence on PSF under drought conditions.
